Abstract：A multi-hierarchy and multi-index comprehensive evaluation system of rock slope is established；and the safety grade standard and the corresponding range of index are suggested as well. Based on matter element theory and the dependent function of extenics set，the extenics evaluation model for rock slope is proposed. Meanwhile，the detailed implementing approach is presented and the relevant numerical computation code is programmed. The method is applied to evaluating the comprehensive safety of the high rock slope on the left spandrel groove of Jinping I hydropower project. It is obtained that the grade eigenvalue is 4.001 and safety grade is IV which means that the comprehensive safety grade of the high rock slope is between hyper-stability and stability. This case has shown that the extenics evaluation model for rock safety is feasible to evaluate the safety of rock slope comprehensively. This method can be applied to evaluating rock slope during construction period of the project and operation period as well.
